Within 3 hours of NYC: Bard, Vassar, Sarah Lawrence, Marist, Skidmore (maybe pushing it), Williams, SUNY schools. Fordham, Hofstra.
Perhaps just a bit further: Connecticut College, Yale, Trinity, Wesleyan, Amherst, U Mass Amherst, the Boston schools, Pennsylvania/New Jersey schools.
I actually think there are a lot of schools within 3 hours of NYC. I am sure he has other criteria; if you share them perhaps people can make suggestions (if you would like, of course).
